When getting vertical via cables, rungs, and ladders, we load up the Deuter Trail SL 22L Backpack. The Active Fit shoulder straps and Airstripes back panel ensure our carry is comfy, breezy, and restriction-free, while the internal frame keeps our load steady. After the approach, we tuck away the hip fins for a more streamlined fit with our harness and secure our trekking poles with the integrated bungee loops.
